Lower limbs rehabilitation exercise apparatus for curvilinear motion

Abstract

Disclosed is a lower limbs rehabilitation exercise apparatus for curvilinear motion. The lower limbs rehabilitation exercise apparatus for curvilinear motion include: a main frame installed in an upward direction; a saddle part located at a front surface of the main frame to support a hip of a user; and a lower limbs exercise part disposed at a side of the main frame to control feet of the user to perform the curvilinear motion.

What is claimed is: 
     
         1 . A lower limbs rehabilitation exercise apparatus for curvilinear motion comprising:
 a main frame installed in an upward direction;   a saddle part disposed at a front surface of the main frame to support a hip of a user; and   a lower limbs exercise part disposed at a side of the main frame to control feet of the user to perform the curvilinear motion.   
     
     
         2 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 1 , wherein the lower limbs exercise part comprises:
 a footrest on which the feet of the user put;   a rail installed therein with the footrest to be freely moved; and   a fixing hinge configured to fix one end of the rail hinge-fixed to a bottom.   
     
     
         3 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 2 , further comprising a third driver fixed to the bottom and connected with the rail to move the rail in upward and downward directions. 
     
     
         4 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 1 , wherein the main frame comprises:
 a hinge shaft spaced apart from a bottom; and   a frame installed upward and including a bottom end hinge-fixed to the hinge shaft.   
     
     
         5 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 1 , further comprising a first driver installed at the main frame to rotate the main frame. 
     
     
         6 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 1 , wherein the lower limbs exercise part comprises:
 a footrest configured to support the feet of the user; and   a pressing part disposed at the footrest to press the feet of the user placed on the footrest.   
     
     
         7 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 6 , further comprising:
 a pressure sensor disposed at the footrest to detect pressure applied by the feet of the user placed on the footrest;   a second driver connected with the saddle part to control a height of the saddle part; and   a controller configured to determine whether the user sits down the saddle part, to compare the pressure detected from the pressure sensor with a reference value to determine whether the user prepares a standing operation, and to raise the saddle part by controlling the second driver to assist the standing operation of the user.   
     
     
         8 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 6 , wherein the pressing part is filled with gas or liquid. 
     
     
         9 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 1 , further comprising a chest support part located above the saddle part to support a chest of the user. 
     
     
         10 . The lower limbs rehabilitation exercise apparatus for curvilinear motion of  claim 9 , further comprising a connector configured to connect the saddle part with the chest support part to move the chest support part according to movement of the saddle part.
